Nowadays good practices promote a business centered approach while designing, implementing and governing architectures. Enterprise Architecture (EA) and Service-Oriented Architecture (SOA) are two popular paradigms that fairlrepresent and walk, in their own way, toward the achievement of this directive.

Although SOA has been well known as an IT-centered methodology, it is clearly documented that the success of such a project relies strongly on the alignment of applications and technology with the needs and requirements of the business. These requirements are meant to be derived directly from its business processes, proving the importance of the robustness of the lather.
Business processes, in turn, should be aligned to the enterprise’s strategy. Following all these leads brings us to the conclusion that EA and SOA are not mutually exclusive but complementary, and can be used together on the enterprise’s transformation projects.

In this talk, we present a case study on the establishment of a new architecture for a financial sector organization, accomplished by the jointuse of both methodologies. Primarily based on The Open Group’s "Using TOGAF® to Define and Govern Service-Oriented Architectures," a Financial Information Service-Oriented System was designed by using EA’s framework TOGAF.

Bio

Andrea Treviño Gavito has been working for the last three years as an Enterprise and IT Architect at Banco de México. Her work has focused on the development and implementation of architecture best practices on Financial Information Systems. She is an Applied Mathematician and Computer Engineer from Instituto Tecnológico Autónomo de México.

Oswaldo Baez, Chief in Financial Information Architecture, has been working for the central Bank of Mexico since 1997. He has been taking part on IT projects that have aimed at the continuous improvement of the processing of data from the local financial system.

He holds a doctorate degree in Computer Science from the University of York at the UK. His subjects of specialization are data management, data mining and neural networks.

Nowadays he runs the office of financial information architecture at the central bank. His current challenge implies the developing of the enterprise architecture responsible for the provision of information products about the local financial system.
